Tryptophan as an Auxin Precursor in Cucumber Seedlings 1

RESUMO
The conversion of tryptophan-14C to indoleacetic acid-14C in cucumber hypocotyls occurred under both sterile and non-sterile conditions. This conversion was not reduced under sterile conditions. The growth response of cucumber hypocotyl segments to exogenously supplied tryptophan was almost as great under sterile conditions as when contaminating micro-organisms were present. These data are consistent with the hypothesis that tryptophan is a normal precursor of indoleacetic acid in cucumber tissues.
